I finally found some time (I don’t know where) and fixed a few of the bugs that had been bothering me most about Zempt. The biggest one was how Zempt would mess up the internal posting date of existing blog entries when you edited them and re-published them.
It turns out that if you return the timestamp using XMLRPC in UTC time without specifying it with a “Z” at the end, WordPress assumes you are using local time … for me, that meant that when I edited a post originally published at 7 p.m., the edited version would be published with the UTC time of +0600 hours. WordPress assumed the posting date was 1 a.m. the next day … so now, Zempt correctly appends the “Z” timezone specification on posts with explicit dates. Wahoo! Plus the upload file tools seems to work pretty solidly for me.
